Ten Bruggencate is a lunar impact crater that lies on the far side from the Earth, just to the east of the younger crater Lane. To the southeast is Chauvenet. This is a worn and eroded formation, with the satellite crater Ten Bruggencate H overlapping part of the side to the east-southeast. There are several small craterlets along the inner wall and the edges of the interior floor. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
